AlM-PROVED MACHlNE FOR BURNISHING BOOT AND SHOE H-EELS.

Specification forming part of Letters Patent N0. 01, H67, dated March 22, i870.

To all whom it may concern:

Be it known that we, J. H. SAWYER, of Boston, in the county of Suffolk, and CHARLES KENISTON, of Somerville, in the county of Middlesex, all in the State of Massachusetts, have invented an Improved Machine for Burnishing the Heels of Boots and Shoes; and we do hereby declare that the following, taken in connection with the drawings which accomnishin g or polishing Wheel, against the periphery of which the edge of the heel is pressed, while theboot is turned to bring the whole length of the edge to the action of the wheel.v

- Although such machine does very good work,

itis defective, in that the laction of the wheel is in, and only in, thedirection of the length of the heel-edge; and as the heel is generally made up of a series of lifts, a lateral motion in the. polisher is necessary to rub dow-n and obliterate, or merge into one smooth surface,

the adjacent edges of the respective lifts.

l Our invention is intended to remedy this defect, and we accomplish the desired result by combining, with a rotary burnishing or polishing wheel, a provision for short lateral re ciprocations of such wheel, so that the polishy ing-surface oft-he wheel acts in both directions, rotating against the heel-edge held against it, (and along the edge thereof as the boot Qr-shoe is turned,) and acting across the edge by its laterall y-reciprocatin g movements.

Our invention consists, primarily, in a machine for burnishing the heels of boots or shoes, having a rotary burnishin g or polishing wheel, to which a lateral reciprocating movement is imparted.

The drawings represent a machine embodying our invention.

A shows a side elevation of the machine. B is a plan of it, the cap to one of the journalboxes of the shaft being removed.

a denotes a suitable bed or frame, having edge of the heel is pressed 11p against the periphery of the wheel; and this guard may be made adjustable in position, relatively to the face of the wheel, by means of screwsand slots g, the slot being made in the arms h, by which the guard is fastened to the adjacent upright b. The shaft d carries a cam-wheel, t',

Vin the perimeter of which is a zigzag camgroove, k, into which extnds a pin, l, projecting from a plate, m, fixed to the frame-work of the machine.

The shaft d ismade to slide in its bearings, as well as to rotate therein; and, as the shaft is rotated, the action ofthe cam-groove k and pin l causes a reciprocating movement to be imparted to the shaft d and Wheel e, as will be readily understood.

The bottom of the heel to be polished being placed against the outer face ot' the guard f, the edge of the'heel is held up to and pressed against the rotaryburnishing-edge of the wheel, the shoe being turned to present all of the heel-edge to the Wheel.

As the surface of the heel-edge is thus acted upon along its whole length, it will be obvious that, under the'reciprocating lateral movement of the wheel across the edge of the heel, the asperities and irregularities of the edges of the respective lifts of the heel will be very quickly solidied, burnished, and run together, so as to form one smooth and unbroken surface, the Wheel being supplied with blacking when necessary to impart the desired color and polish to the heel.

In order that there shall not be a dead or unyielding surface against which to hold the heel-edge, We mount the bearings of the shaft d with provision for slight play, placing between the sides of the front box or bearing and the adjacent surface of the housing springs n, whichvpermt the shaft and its burnishingwheel to yield slightly under pressure, this Aprovision being applicable to burnishingwheels having no reciprocating movement, as well as such as are arranged as shown.

To enable the wheel e to be heated, it may be made hollow, or as a shell, open at its inner end, as seen at A, sothat a gas jet or tip can enter the wheel, and .cause its ame to impinge upon and heat the wheel, as will be readily seen.

The shaft e may carry a polishing-brush, o,

to nish off the heels burnished by thewheel e.
